Noob question

Ok here the deal. I bought this car (in sig) from Chicago. Lots of aftermarket engine parts. Tuned from Moates Tuner Pro R/T software.

Okay, now back at home the altitude (well density altitude) is 5000 ft (most of the time) Could this custom tune account for that?

Or could that be part of why the car isn't preforming as it should?

Re: Noob question

i have never messed with tuning for different altitudes, so i don't know if the ECM can completely compensate for it on a modded motor.

i have driven at higher altitudes, i did notice a major drop in performance.
